There are many hung threads on my BES Server. Found that i have some terminated/disabled users.
I get events like 50020 & 20154 in my App log.
I restarted the server twice and still have the hung threads.

1) Can anyone help me out to solve the hung thread issue?
2) Is there any command on the BES so that i can delete all the disabled AD users from my Blackberry Manager?

Do you really have that many users? Do my favorite trick ... fire up the BES Manager, look for anyone that hasn't had contact for 30 days and remove them from the BES. Then anyone on the cusp; check them out individually.
